What is going on with this game, programming is so sloppy…
It’s a temporary fix to a bug. There was a bug that allowed a player to duplicate an item and use them in campaign. Some people knew how to use these as fusing material and the developers had to temporarily change it to the same sprite as the War Hammer.
It will change back soon.
That makes zero logic.
Uh, OK then…
Sorry, let me clarify.
The glitch was caused because of a bug that came with the design of the axe. The devs had to change it to the hammer again to remove the design AND the bug entirely. Otherwise, players would have endless items.
